Mapefloor I 302 SL Do not apply on substrates that have not been treated with Primer SN or with another recommended primer or that have not been prepared as specified. Do not mix partial quantities of the components to avoid mixing errors; the product may not harden correctly. Do not expose the mixed product to sources of heat. Coatings made from may change colour or fade if exposed to sunlight but this has no effect on its performance characteristics. The coating may also change colour if it comes into contact with aggressive chemicals. A change in colour, however, does not mean that it has been damaged by the chemical. If rooms where the product is being applied need to be warmed up do not use heaters that burn hydrocarbons, otherwise the carbon dioxide and water vapour given off into the air will affect the shine on the finish and ruin its appearance. Use electric heaters only. Remove aggressive chemicals as soon as possible after they come into contact with. Use suitable specific cleaning equipment and detergent to clean the coating, depending on the type of dirt or stain to be removed. Protect the product from water for at least 24 hours after application. Do not apply the product directly on substrates with moisture content higher than 4% and/or with capillary rising damp (check by testing it with a sheet of polythene). The temperature of the substrate must be at least 3 C above the dew-point temperature. APPLICATION PROCEDURE Substrate preparation Surfaces to be treated with this product must be flat, clean and dry and must have no capillary rising damp. Also, the substrate screed must be strong enough to withstand the loads to which it will be subjected when in service. Any cement laitance present on the surface to be treated must be removed mechanically. Any cracks must be repaired by filling them with Eporip, while any deteriorated areas of the concrete must be repaired with Mapefloor EP19 or a cementitious mortar from the Mapegrout range. Before applying, all traces of dust must be removed from the surface with a vacuum cleaner and substrates must receive adequate preparation and be treated with primer. Application of Primer SN Apply the Primer SN as is or mixed with Quartz 0.5 on the substrate after it has been prepared as specified with a smooth spreader or rake. Immediately after applying Primer SN broadcast the surface while still wet with Quartz 0.5, depending on the type of coating to be applied. Make sure there are no open pores in the surface of the substrate otherwise air bubbles could escape and form small craters or pinholes in the self-levelling finishing coat. If there are holes or open pores in the substrate fill them with Eporip or Primer SN thickened with Additix PE. Preparation of the product The two components which make up must be blended together just before application. Briefly mix component A, add component B (catalyser), quartz sand where required and mix with a drill at low-speed to prevent entraining air into the mix until it forms a smooth, even paste. Pour the mix into a clean container and mix again for a short time. Application of the product may be used to form non-slip, multi-layer coatings (0.8 to 3.5 mm thick), or self-levelling coatings (2 to 3 mm thick). The application procedures are as follows: 1. Non-slip multi-layered coating - 0.8 to 1.2 mm thick Prepare the substrate by shot-blasting or grinding with a diamond disk and remove all traces of dust with a vacuum cleaner. With a straight trowel apply a skim coat of Primer SN mixed with Mapecolor Paste and with 20% by weight of Quartz 0.5; immediately after applying the primer, fully broadcast the surface with Quartz 0.5. When the primer has hardened remove any excess sand, sand the surface and remove the last grains of sand with an industrialgrade vacuum cleaner. Depending on the degree of non-slip finish required, apply a finishing coat of neat by medium-pile roller or scratching to zero with a straight trowel. Then backroll with a short-pile roller in a criss-cross pattern. 2. Non-slip multi-layered coating - 3.0 to 3.5 mm thick Prepare the substrate by shot-blasting or grinding with a diamond disk and remove all traces of dust with a vacuum cleaner. With a straight trowel apply a skim coat of Primer SN mixed with 20% by weight of Quartz 0.5; immediately after applying the primer, fully broadcast the surface with Quartz 0.5. When the primer has hardened remove any excess sand, sand the surface and remove the last grains of sand with an industrialgrade vacuum cleaner. Apply Mapefloor I 302 SL mixed with 50% by weight of Quartz 0.5. Pour the product over the floor and spread it evenly with a straight steel trowel. Fully broadcast the surface of Mapefloor I 302 SL, while still wet, with Quartz 0.5. When the product has hardened, remove any excess sand and sand the surface removing the last grains of sand with an industrial-grade vacuum cleaner.

Smooth self-levelling coating - 2-3 mm thick Prepare the substrate by shot-blasting or grinding with a diamond disk and remove all traces of dust with a vacuum cleaner. With a straight trowel apply a skim coat of Primer SN, mixed with 20% by weight of Quartz 0.5; immediately after applying the primer, lightly broadcast the surface with Quartz 0.5 at a rate of up to 0.5 kg/m². For particularly porous substrates the surface will need to be primed several times, without broadcasting the surface with sand, until all the pores in the substrate have been completely filled. When the primer has hardened remove all the loose sand with a vacuum cleaner and apply the self-levelling layer of mixed with up to 50% by weight of Quartz 0.25, depending on the surrounding temperature. Pour the mix onto the floor and spread out evenly using a notched spreader (with V shaped teeth). Backroll with a spiked roller several times while the product is still wet to even out the thickness of the coating and to remove any air entrained into the product during the mixing phase. N.B.: the examples above are for indication purposes only. The amount of sand added to the Primer SN or may vary according to the surrounding temperature. The amount required may be less at lower temperatures and more at higher temperatures. CONSUMPTION 1.
